CONTINUOUSLY -OPERATING MACHINE FOR PHOSPHATING AND WASHING FABRICS.

Application filed September 4, 1926, Serial No. 133,586," and in France September 19, 1925.

This invention relates to a continuously operating machine for phosphating and washing fabrics, or for immersing fabrics freely for a variable tlme 1n a succession 5 of different baths.

In-order to preserve the particular appear-.

ance of certain fabrics; crepe de chine, for

example; they must be submitted to a suc cession of washing operations and immersed in a phosphating bath, where they should be able to contract freely. This treatment actually necessitates an important hand op eration and voluminous apparatus.

The object of the present invention is to provide a continuously operating machine carrying out mechanically the different operations of washing and-phosphating, and thus ermitting an increased manufacturing yleld with a decreased hand operation and material of small bulk.

The machine under consideration is es sentially formed with a central drum immersed in a phosphating bath and having an intermittent or difierential movement, 0bt ained by means of an endless cloth, which holds between itself and the periphery of the drum the folds of fabric given out at constant speed and previously washed by ramps formed around the periphery of a leading drum, the cloth being finally washed immersions in a reservoir hav by successive in a double compartment.

The annexed drawing shows,

by way of example,

one practical embodiment of the in- On the drawing Fig. 1 is a longtiudinal view of the whole machine:

Fig. 2 is a plan; and a Fig. 3 shows the-@details of the control mechanism for the phosphating bath.

Figure 4 is an enlarged sectional view of the central drum and accessories.

Referring to the drawing The -machine comprises a distributing roller 11, .a curved spreading tube 6, fol-' lowed by a second cylinder 0, beneath which are disposed two ramps 0, and a drum whose periphery is formed by bars (2. This drum 5 is mounted loosely on its shaft, and around 7 itare arranged concentric ramps e, projecting hard water. Above the drum are fixed two washing ramps e, fed by soft water, and between which the fabric to be treated passes. Above these ramps is mounted a cylinder f, followed by two rollers h, k, forced a stretching. cylinder r of a roller 8 operated Z; driven by an eccentric u mounted on the shaft of a roller m,,the slight rotation of against each other by a counterweight h". The frame of the machine'also supports a phosphate bath i in which is arranged a drum formed with a cloth zstretched on to concentric bars 71'. This drum is driven by an endless cloth is mounted on cylinders I0 I1 I0 70*, k is, and controlled by means of two chains, fixed to its edges, through toothedwheels. Above the cylinder 70' is disposed a roller Z, and a perforated tube Z serving to project the phosphated solution. On the roller Z are formed circular grooves in which combs, or any other device which will ensure the taking off of the fab- ]rcic, engage. Between the two rollers Z and 7 followed by two rollers m, m pressed against each other by a counterweight'm". The frame also supports a washing vat n with is mounted a curved spreading-tube Z",

two compartments, provided at its bottom 4 rollers 11,, arranged 11." disposed above the At the outlet of the vat are disposed two washing tubes n cylinders 0, 0

which are followed by two arranged above a trough 1' containing acid liquid and comprising a bottom roller 1" and a top roller 1 followed by As shownin Fig. 3, the rotation of the cylinder k drawing the endless cloth in is controlled by the aid alternatively by a lever the cam being controlled b gears a, u", o and 'v'. The pressing cylin ers and the driving of the machine are operated by a series of bevel wheels shown in Fig. 2.

As is easyto understand from Fig. 1, the fabric .2 led fromthe cylinder 0; is spread out by the curved tube 1) on to the second cyllnder 0 and passes over the drum where it is sprinkled by the ramps 0' and 6' projecting hard water. Leaving the drum the fabric is washed by the two ramps 6' projecting soft water. The fabric is then rolled over the cylinder Z where it is drawn at a constant speed and from which it is disengaged by the combs Z In consequence of the intermittent movement of the drum i by the driving of the endless cloth is, the fabric fed by the rollers h and Z simultaneously driven by beveled gears as shown in Figure 2 is disposed in folds on the periphery of the drum when the latter is stacommunicated thereto provided with intermittently tionary. The successive displacements of the drum thus determine a series of superposed folds 2, which are maintained between the endlesscloth hand the drum 2''. There results a free immersion in the phosphating bath whose duration is proportional to the speed of the drum 1'. By modifying the ratio of the gears for the cam movement, it is possible to vary at will the speed of the drum i.

The fabric 2 previously sprinkled by the perforated tube Z,,which projects a phos phated solution, passes from the exit of the vat i on to the spreading tube Z so as to be pressed between the rollers m, m. and drawn into the washing bath constituted by the two compartments of the vat a. ()11 leaving the latter, the fabric is rinsed by the two perforated tubes n and then plunged into the acid bath of the reservoir 1', after which itis folded so as to be ready to undergo fresh operations.

It willbe understood that the machine is also applicable to all dyeing operations. it can comprise any desired number of baths moving drums, the speed of which can be proportioned to the time necessary for the penetration of the products.

The phosphating drum can also turn continuously at a uniform speed less than that of the fabric, which is thus retained in folds around the periphery of the drum.
